Definitions
- the present invention relates to a method for machining an internally toothed workpiece and a tool and a
- an internally toothed workpiece in which the workpiece is clamped in a gear honing machine, and wherein at least one tool, which consists at least partially of a high-hardness cutting material, is guided along respective teeth of the internally toothed workpiece to perform a hard fine machining of the teeth of the internally toothed workpiece.
- the proposed method is used in particular for hard finishing a hardened internally toothed gear in a fast process, which is also suitable for use in mass production.
- a respective internally toothed gear wheel or ring gear is used in a gear honing machine, in particular at the location of a honing ring, and at least one tool, which consists at least partially of a high-hardness cutting material, is guided along respective teeth of the gear, so that the at least one tool when moving along the teeth of the gear penetrates into respective spaces between the teeth and takes place on the respective flanks and / or possibly tooth roots of the teeth material removal.
- a toothed honing machine is used to carry out the presented method, which moves the inventively provided at least one tool with a machine kinematics, which is provided for a method for power honing, so that on the gear honing machine for the
- a respective internally toothed gear to be machined in a cutting process with a geometrically undefined cutting edge.
- polycrystalline diamond or in particular cubic boron nitride (cBN) is selected as a high-hardness cutting material.
- the tool By means of a tool which exceeds in its dimensions, in particular in its width, the dimensions of a respective workpiece, it is possible to move the tool on the workpiece so that the tool contacts the workpiece with different areas and processed accordingly.
- the tool may be wider than the workpiece and corresponding to the workpiece in the axial direction, in particular along a horizontal or vertical axis passing through a center of the tool axis, or a change of a respective Achsnchwinkels relative to the workpiece, depending on the desired
- an Achsnchwinkel the at least one tool is changed to the workpiece, so that the workpiece contacts the at least one tool at a predetermined point.
- the tool is displaced axially along an axis extending horizontally or vertically through a center of the tool so that the workpiece contacts the at least one tool at a predetermined point.
- Tool is moved as a whole relative to the workpiece to adjust a contact point of the tool with the workpiece.
- the at least one tool along a longitudinal axis of the at least one tool with different areas
- the at least one tool is moved in a predetermined sequence of movements along the workpiece to the workpiece successively with respective areas of the at least one tool, the different Have surface properties, contact and edit accordingly.
- the machining can take place in a continuous movement as well as in an interrupted cut. In this case, the processing, in particular for improving surface properties of the
- the tool may have a plurality of regions with, for example, different roughness, which contact one another in succession or alternately be brought by the tool in particular axially, d. H. along, for example, an axis extending vertically or horizontally through a center of the tool, displaced with respect to the workpiece, or changing an axis cross angle of the tool relative to the workpiece.
- a respective tool for example, first a roughing process and then a finishing process can be performed.
- the at least one tool provided according to the invention has a plurality of areas of equal roughness and the at least one tool is moved such that a contact point of the at least one tool changes with the workpiece, so that the at least one tool over time a plurality of locations comes into contact with the workpiece and individual points or areas of the at least one tool are relieved, thereby increasing a service life of the at least one tool compared to a method with a permanent contact at one point or in one area.
- At least one dressable tool is used, which by means of a Dressing tool, ie to profile and / or sharpening is. It is of course conceivable that the at least one tool is trained in areas, while the at least one tool is moved along a respective workpiece to a respective contact point between the at least one tool and the
- dressing in the context of the present invention means a process in which a tool is re-profiled or calibrated.
- the present invention relates to a tool for machining an internally toothed workpiece, wherein the tool consists at least partially of a high-hardness cutting material.
- the presented tool is used in particular for carrying out the presented method. In a possible. Embodiment of the presented tool is provided that the tool is configured to each one
- the presented tool has in particular the form of a
- the present invention relates to a gear honing machine with a receptacle for a workpiece and a dressing tool, wherein the dressing tool is configured to at least a tool to be guided inwardly on a workpiece to be introduced in the recording tool, which consists at least partially of a high-hardness cutting material, at least partially.
- the presented gear honing machine is used in particular for
- a dressing tool such as. A dressing roller, in particular movable on the inventive
- the inventively provided tool can be dressed efficiently and without tool change.
- the dressing tool may be shaped like a grinding worm during generating grinding to allow rapid dressing in a continuous process.
- Gear honing machine is provided that recording a
- a honing ring is to be used for machining an externally toothed workpiece in a honing operation of the gear honing machine.
- a gear honing machine that is configured to honing an externally toothed gear is reconfigured to a possible embodiment of the presented gear honing machine by replacing a honing ring of the gear honing machine by a workpiece and a possible embodiment of the
- inventive tool is positioned on the workpiece.
- FIG. 1 shows a possible embodiment of a tool according to the invention configured to carry out a possible embodiment of the presented method.
- FIG. 1 shows a workpiece 1 in the form of an internally toothed gear wheel. The workpiece 1 was in a not shown
- Gear honing machine is used for honing.
- respective teeth ie in particular tooth flanks and / or feet of the workpiece 1
- a tool 3 is introduced to a position of the gear honing machine, on which a workpiece is traditionally clamped when the
- Gear honing machine is used for honing.
- the tool 3 can be moved along an axis 15 of the tool 3, as indicated by arrow 13.
- the workpiece 1 can also be moved itself, as indicated by arrow 7, to assist a rolling movement of the tool 3 on the teeth.
- the workpiece 1 comprises on each tooth tooth flanks 9, which consist of hardened material.
- the tool 3 comprises a coating of a high-hardness or high-strength cutting material, such as diamond or boron nitride.
- the tool 3 is for a flank contact, i. H. a
- the tool 3 Machining only one tooth flank 9 per movement of the tool 3 configured.
- the tool 3 may also be configured to have two tooth flanks 9 and / or a tooth root 1 1 of the workpiece 1 per movement, d. H. when immersed in a recess formed between two teeth.
